I once serviced a Stwy M that had the top end of the bridge end binding against the plate giving the bi-chords a deader and a deader sound playing upwards towards note 26. I Inserted hacksaw blade between plate and bridge and set it free. No more thunk thunk I was surprised that it got past  past quality control and others for 20 years naaaaaaah it happens. >>>>>>>>>Dale Erwin>>>>>>>>>> <BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px"> Sounds like it could be the bass bridge / apron.

Steck small grand. The bass strings can't be as old as the piano. They are still copper-colored and "look" fairly clean etc. But when struck, the bichord notes have very little sustain. The singles do better. The tenor and treble sounds great, very sweet actually. I tried the old remove-loop-and-roll on the worst note. The string looks a little brighter but I can't tell much difference in the sound. Any ideas? I wondered about a downbearing problem or something but would assume such a design flaw would be unlikely.
